Abstract

In each terminal connected to an optical bus a narrow pulse synchronized with the rise of a pre-synchronizing pulse appended to the head of the one digital signal TXN of Manchester-biphase signals, a narrow pulse synchronized with the rise of each pulse of the other Manchester-biphase digital signal TXO and a narrow pulse occurring every fixed period of time during the duration of each pulse are produced, and these narrow pulses are converted into optical signals, which are provided as an optical pulse train to the optical bus. In each terminal optical pulses received from the optical bus are converted into an electric signal, which is separated into its leading pulse and the subsequent pulses, and the synchronizing pulse is produced in synchronization with the leading pulse and the subsequent pulses are each converted into a pulse of a fixed width to regenerate the signal TXO, and the regenerated signal TXO is polarity inverted and is then combined with the pre-synchronizing pulse to regenerate the signal TXN.
